To all 1071 0772, it nmq concern:

Be it known that we, HENRY ARIENS and J OHN THoMrsoN, citizens of the United States, and residents of Brillion, in the county of Oalumet and State of W'isconsin, have invented certain new and useful Improvements in Pulverizers; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention consists in certain peculiarities of construction and combination of parts hereinafter particularly set forth, with reference to the accompanying drawings, and subsequently claimed, the object of the invention being to improve soil-pulverizers of the type disclosed in Patents No. 695,025, of March 11, 1902, No. 717,653, of January 6, 1903, and No. 727,25et, of May 5, 1903.

Figure 1 of the drawings represents a side elevation of our improved pulverizer, partly broken and in section; Fig. 2, a plan view of the same, partly broken and in section; Fig. 3, a partly-sectional view of a fragment of the machine and is indicated by line 3 3 in Fig. 1; Fig. 4, a detail view indicated by line 4 4 in Fig. 2; Figs. 5, 6, and 7, detail views, respectively, indicated by lines 5 5, 6 6, and 7 7 in Fig. 1; and Fig. 8, a like view indicated by line 8 8 in Fig. 1.

Referring by letter to the drawings, A indicates each of a pair of side castings, and B each of a pair of angle-iron beams bolted at their ends to upper corners of the castings to constitute a frame the same as in Patent No. 717,653 above noted, except that the boltopenings in the castings are elongated, as shown at d, to provide for an adjustment of said castings longitudinally of the beams. The same result may be obtained by elongating the bolt-openings in the beams; but it is preferable and more economical to elongate the bolt-openings in the side castings aforesaid.

The forward upper arms of the castings A below the front beam of the machine are provided with outer lateral pivot-studs 0, that engage eyes in the forward ends of the rearwardly-extending side castings O of said machine. A bolt (Z extends through the pivoting of each casting A, and a washer e on the bolt opposes the corresponding casting O, a nut f being run on said bolt against the washer.

The two rearwardly-extending castings O are connected by an angle-iron beam D, bolted to their upper rear corners to constitute a frame the same as in Patent No. 717,653 aforesaid, except that the bolt-openings in the castings or beam, but preferably in said castings, as shown at b, are elongated to provide for adjustments of these castings.

Brace-rods E connect the side castings O and beam D, these rods being shown headed on said beam and having screw-threaded ends extended through apertures in said castings to receive tension-nuts 9, this detail of construction being best shown in Figs. 3 and 5.

The usual bearing-boxes for disk shafts F G are feather-keyed or otherwise secured against rotary movement in lower apertures of the pivotally-connected side castings, and a vertically-disposed oil-feed tube H is cast in each of said boxes. The disks herein shown are loose on their shafts between washers K, that are provided with hubs having alined notches of different depths therein, and split spring-keys L or other suitable holding devices are engaged with hub-notches and shaftapertures. Owing to variation of thickness on the part of the cast sections of the disks, said disks will take up more or less space lengthwise of their shafts, and hence the holding devices L are engaged with those washerhub notches that will best register with the shaft-apertures. The side castings A and O of the frames aforesaid are adjusted to bring the bearingboxes therewith close to the washer-hubs. As is customary in the art, the disks of one set are arranged to out between those of the other.

A rocker M is held in connection with the rear beam D by a shackle N, bolted to said beam central of the same. Bolted to the rocker is a suitably-bent cross-bar P and a seat-support Q, the bent cross-bar being extended in opposite directions from the seatbar to form rests for the feet of the driver of the machine. A pair of parallel slides R are adjustable on the seat-support and clamped thereto in any position of their adjustment by means of bolts and nuts. A brace-rod S connects the forward bolt for the slides R with an eyebolt k of a draft-tongue T, that it bolted to the beams B aforesaid. A plate U in adjustable connection with the draft tongue longitudinally of the same is connected by brace-rods V with the front one of the beams B, said plate being adjusted to regulate the tension of said brace-rods in connection therewith. The weight of the driver on the seat W exerts a leverage that tends to compensate for weight that would otherwise come upon the front shaft F, the machine being thus balanced when in use. The seat-support being in rocking connection with the rear beam D of the machine, it readily conforms to tilting motion of the draft-tongue, to which it is connected by the means above specified.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is*

l. A soil-pulverizer comprising forward and rear frames in pivotal union, shafts having their hearings in the frames, disks on the shafts, a draft-tongue in connection with the forward frame, a rocker shackled on the rear frame, a seat-support in connection with the rocker, a brace-rod fastened at one end to the draft-tongue, and means by which the other end of the brace-rod is put into adjustable connection with the seat-support longitndi- HENRY ARIENS.
